SkuRay is a free calculator that estimates margin, ROI, and net profit for products sold via Amazon FBA, based on data the user manually enters (price, costs, fees, return rates, etc.).
All results shown by the calculator are estimates based on the data you enter. They do not constitute financial, accounting, legal, or any other type of advice. Amazon fees, exchange rates, freight costs, and other variables may differ from actual values depending on your account, category, location, and timing. Before making purchasing or investment decisions, confirm exact figures in Seller Central and with your own suppliers.
SkuRay is not responsible for losses, purchasing decisions, or business outcomes resulting from the use of this tool. Use of the estimates provided by the calculator is the sole responsibility of the user.
The calculator runs entirely in your browser. Calculations you save in the folders section are stored only in your browser's local storage (localStorage) — nothing is sent to any server, we don't see it, and it isn't shared with third parties. If you clear your browser cache or switch devices, that data is lost.

This site does not use first-party cookies for the calculator's functionality. Third-party services integrated (such as Google Fonts or Google Analytics, if active) may set their own cookies per their policies.
